A retired school psychologist whose pooch escaped from her home while she was on vacation claims that animal-rescue workers refused to give the dog back, and instead gave him up for adoption.

Glenrose King-Alleyne was on a weeklong trip in July and left the 9-year-old cocker spaniel with her brother Winston at his Brooklyn home.

But Winston had a stroke on July 31, and Sidney (pictured) bolted when medics left the door open.

He was captured a few days later by NYC Animal Care & Control, according to the suit filed yesterday by lawyer Lori Lefkowitz in Queens Supreme Court.

King-Alleyne returned from vacation Aug. 4 and, armed with proof of ownership, tried to reclaim her pet, but got the runaround from the group’s founder, Dolores Rodriguez, the suit charges.

“I’m really stressed out. I’m still trying to find him, but they won’t tell me where he is,” King-Alleyne said.

In an e-mail to The Post, Rodriguez said, that King-Alleyne is Sidney’s rightful owner, but charged that she didn’t take proper care of the pup, which she said suffers from a heart murmur and dirty choppers.“We are willing to consider transferring legal ownership of the animal back to her once his medical issues have been addressed.”
